Seed zones and breeding zones for white pine in the Cascade range of Washington and Oregon

Government Document
Transfer Guideline

Pacific Northwest, USA

Provisional seed zones and breeding zones were developed for white pine (Pinus monticola Dougl. ex D. Don) in the Cascade Range of western Washington and Oregon. Recommendations were based on genetic variation patterns obtained by evaluating genotypes of trees from 115 locations. Genotypes controlling growth vigor and growth rhythm were assessed in common gardens. Five zones, delimited mainly by latitude, were recommended: two in Washington, two in Oregon, and one in both States adjoining the Columbia River.
